MySQL Connector Java 8.0.18 - Time Zone is unrecognized - mysql

I am working on upgrading existing libraries in our code and mysql-connector-java is one of them. We currently use the version: 5.1.25, I am trying to upgrade it to the latest version which is 8.0.18. I got some errors regarding to package structure changes but I've corrected them.
When I run the application (directly goes go database for authorization) I get following error:
The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
After some research I've found this question and realized I have to specify server time zone. Our database both on development and production environment configured as CEST time zone but when I add "serverTimeZone = CEST" to connection string I get following error:
No timezone mapping entry for 'CEST'
If I specify like "serverTimeZone = UTC", it works but confuses me also.
Why should I say UTC even though it is CEST? Time zone in my local system is UTC, is it the reason that I have to force it to UTC? If so, we have users all around the world, so bunch of request from different time zones will come to the DB server, if I say serverTimeZone = UTC, isn't it going to be a problem for them?

Streampipes MYSQL Set Adapter - Stream Adapter

I am trying to connect Apache streampipes with a MySQL Database.
I am getting the following :
org.apache.streampipes.connect.api.exception.AdapterException: Could not connect to server: The server time zone value 'EEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
How can i solve it ?

Why timestamp in MySQL JDBC have to be corrected with 'GMT-6:00'?

I have a table contains a regular datetime typed column, and when selecting mysql command line returns the correct result:
but when it comes to JDBC, it'll return 2020-02-03 08:00:00. I have to use TimeZone.setDefault(TimeZone.getTimeZone("GMT-6:00") to regulate it.
On my server, the time zone related options are:
But seems the result JDBC driver returns is neither in my current time zone, nor the UTC. Is this because of something wrong on my MySQL server...?
Currently I'm using mysql:latest on Docker Windows and mysql:mysql-connector-java:8.0.19, the TZ environment of Docker container has been set to my local time zone.
Many thanks.

The server time zone value 'KST' is unrecognized: How to fix server-side?

I am running a MySQL client utility, and getting this well-known error:
The server time zone value 'KST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
Out-of-the-box Ubuntu 2019.04 with the database engine installed from the official Ubuntu repository (mysql Ver 14.14 Distrib 5.7.26).
How to fix it?
Appending &serverTimezone=UTC to the JDBC URL would fix the problem but unfortunately I can not control the URL used by the utility so I have to work around the problem server-side.
I tried running SET time_zone = "+09:00"; on the MySQL server, it does not fix the problem.
This might be part of the problem:
select * from mysql.time_zone_name;
Empty set (0.00 sec)
env | grep KST returns nothing.

If by KST you mean Korea Standard Time as used in South Korea, use the TZDB identifier Asia/Seoul.
SET GLOBAL time_zone = 'Asia/Seoul';
KST isn't a valid TZDB identifier.

Thank you Mark Rotteveel and Gord Thompson
I have the connection in an XML file, with & and Europe/Amsterdam finally works.

Thank you, you are great

I faced this issue when I upgraded my mysql server to SQL Server 8.0 (MYSQL80).
The simplest solution to this problem is just write the below command in your MYSQL Workbench -
SET GLOBAL time_zone = '+5:30'
The value after the time-zone will be equal to GMT+/- Difference in your timezone. The above example is for India(GMT+5:30).
It will solve the issue.

Find what is the timezone you are in and replace +00:00 with your timezone.
SET ##global.time_zone = '+00:00';
SET ##session.time_zone = '+00:00';
Then check if the values were set:
SELECT ##global.time_zone, ##session.time_zone;

If you are using MySQL client eg. DBeaver you should change settings of your connection. So, click right click mouse on the connection and click Edit Connection. Then, edit your driver properties which are located under the "Connection settings", go to the bottom of settings and click "Add new property", add serverTimezone as your new property name and enter value eg. Europe/Warsaw.
That's all.

How can I tell mysql the timezone throught connection string?

For some reason I am getting this error while trying to start my java app.
java.sql.SQLException: The server time zone value 'AEDT' is
unrecognized or represents more than one time zone. You must configure
either the server or JDBC driver (via the serverTimezone configuration
property) to use a more specifc time zone value if you want to utilize
time zone support.
I would like to be able to change the timezone on the connection string. So far I tried this:
javax.persistence.jdbc.url"
value="jdbc:mysql://localhost:3306/returnit?useLegacyDatetimeCode=false&serverTimezone=UTC"
and this:
javax.persistence.jdbc.url"
value="jdbc:mysql://localhost:3306/returnit?useLegacyDatetimeCode=false&serverTimezone=Australia/Sydney"
But for some reason mysql is not picking up the timezone and still complains about AEDT?
Mysql connector version is 6.0.6
System I am running in MacOS

QUESTION: Any idea about how to setup serverTimezone through connection string?
thank you very much

this is an example of a connection string specifying serverTimezone:
"jdbc:mysql://localhost:3306/returnit?useSSL=false&useUnicode=true&serverTimezone=UTC"
